  • Title: [Photorefractive keratectomy to correct myopic astigmatism].

    Journal: Hunan Yi Ke Da Xue Xue Bao; 1997; 22(5):465-6. PubMed ID: 10073040.
    Abstract:
    The VISX 20/20 excimer laser was used to treat 260 eyes with myopia and myopic astigmatism of 166 patients. All patients were followed up for one year. The diopter of preoperative astigmatism was from -0.25-(- 4.00 D (-1.00 +/- 0.62 D). The diopter was lowered to -0.07 +/- 0.40 D at 6 months postoperatively (P < 0.05) and -0.06 +/- 0.39 D at 12 months postoperatively (P < 0.01). Photorefractive keratectomy (PRK) is effective and safe for myopic astigmatism.
